REGULATORY GUIDE 1

The U.S. Nuclear Regulatory Commission (NRC) issues regulatory guides to describe and make available to the public methodsthat the NRC staff considers acceptable for use in implementing specific parts of the agency’s regulations, techniques that thestaff uses in evaluating specific problems or postulated accidents, and data that the staff needs in reviewing applications forpermits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methodsand solutions that differ from those set forth in regulatory guides will be deemed acceptable if they provide a basis for thefindings required for the issuance or continuance of a permit or license by the Commission.

This guide was issued after consideration of comments received from the public.

Regulatory guides are issued in 10 broad divisions: 1, Power Reactors; 2, Research and Test Reactors; 3, Fuels and MaterialsFacilities; 4, Environmental and Siting; 5, Materials and Plant Protection; 6, Products; 7, Transportation; 8, Occupational Health;9, Antitrust and Financial Review; and 10, General.

Electronic copies of this guide and other recently issued guides are available through the NRC’s public Web site under theRegulatory Guides document collection of the NRC’s Electronic Reading Roomat http://www.nrc.gov/reading-rm/doc-collections/ and through the NRC’s Agencywide Documents Access and ManagementSystem (ADAMS) at http://www.nrc.gov/reading-rm/adams.html, under Accession No. ML072070407.

REGULATORY GUIDE 1.84(Draft was issued as DG-1133, dated October 2006)

DESIGN, FABRICATION, AND MATERIALS CODE CASEACCEPTABILITY, ASME SECTION III

A. INTRODUCTION

General Design Criterion (GDC) 1, “Quality Standards and Records,” of Appendix A, “GeneralDesign Criteria for Nuclear Power Plants,” to Title 10, Part 50, of the Code of Federal Regulations(10 CFR Part 50), “Domestic Licensing of Production and Utilization Facilities” (Ref. 1), requires, in part,that structures, systems, and components important to safety be designed, fabricated, erected, and testedto quality standards commensurate with the importance of the safety function to be performed. Wheregenerally recognized codes and standards are used, Criterion 1 requires that they be identified andevaluated to determine their applicability, adequacy, and sufficiency and be supplemented or modified asnecessary to ensure a quality product in keeping with the required safety function.

Criterion 30, “Quality of Reactor Coolant Pressure Boundary,” of Appendix A to 10 CFR Part 50requires, in part, that components that are part of the reactor coolant pressure boundary be designed,fabricated, erected, and tested to the highest practical quality standards.

Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Processing Plants,”to 10 CFR Part 50 requires, in part, that measures be established for the control of special processing ofmaterials and that proper testing be performed.

RG 1.84, Rev. 34,

Provisions of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel(BPV) Code have been used since 1971 as one part of the framework to establish the necessary design,fabrication, construction, testing, and performance requirements for structures, systems, and componentsimportant to safety. Among other things, ASME standards committees develop improved methods for theconstruction and inservice inspection (ISI) of ASME Class 1, 2, 3, MC (metal containment), and CC(concrete containment) nuclear power plant components. A broad spectrum of stakeholders participate inthe ASME process, which helps to ensure that the various interests are considered.

The regulation in 10 CFR 50.55a(c), “Reactor Coolant Pressure Boundary,” requires, in part, thatcomponents of the reactor coolant pressure boundary must be designed, fabricated, erected, and tested inaccordance with the requirements for Class 1 components of Section III, “Rules for Construction ofNuclear Power Plant Components,” of the ASME BPV Code (Ref. 2) or equivalent quality standards. The ASME publishes a new edition of the BPV Code, which includes Section III, every 3 years, and newaddenda every year. The latest editions and addenda of Section III that the U.S. Nuclear RegulatoryCommission (NRC) has approved for use are referenced in 10 CFR 50.55a(b). The ASME also publishesCode Cases quarterly. Code Cases provide alternatives developed and approved by ASME. This regulatory guide identifies the Code Cases that have been determined by the NRC to be acceptablealternatives to applicable parts of Section III. Section III Code Cases not yet endorsed by the NRC may beimplemented through 10 CFR 50.55a(a)(3), which permits the use of alternatives to the Coderequirements referenced in 10 CFR 50.55a provided that the proposed alternatives result in an acceptablelevel of quality and safety, and that their use is authorized by the Director of the Office of Nuclear ReactorRegulation.

The ASME Code is incorporated by reference into 10 CFR 50.55a. Code Cases approved by theNRC provide an acceptable voluntary alternative to the mandatory ASME Code provisions. Therefore,the NRC will amend 10 CFR 50.55a to incorporate by reference the new Code Cases and revisions toexisting Code Cases listed in this guide, and to state the requirements governing the use of Code Cases. Because of continuing change in the status of Code Cases, the staff plans periodic updates to 10 CFR50.55a and this guide to accommodate new Code Cases and any revisions of existing Code Cases.

1 Except for Code Cases pertaining to high-temperature gas-cooled reactors; certain requirements in Section III, Division 2, not endorsed by the NRC; liquid metal; and submerged spent fuel waste casks.

RG 1.84, Rev. 34,

B. DISCUSSION

Regulatory Guide 1.84 lists all Section III Code Cases that the NRC has approved for use. ForRevision 34 of the guide, the NRC staff reviewed the Section III Code Cases listed in Supplements 7–12to the 2001 Edition of the ASME BPV Code and Supplement 1 to the 2004 Edition.1 Appendix A to thisguide lists the supplements reviewed, the applicable edition, and the date on which each supplement wasapproved by the ASME Board on Nuclear Codes and Standards. Appendix B is a list of the Section IIICode Cases addressed in the seven supplements. Finally, Appendix C is a current list of all Section IIICode Cases. The Code Cases addressed by this regulatory guide are listed in five tables:

(1) Table 1, “Acceptable Section III Code Cases,” contains the Code Cases that are acceptable to theNRC for application in the design and construction of light-water-cooled nuclear power plants.

(2) Table 2, “Conditionally Acceptable Section III Code Cases,” contains Code Cases that areacceptable provided that they are used with the identified limitations or modifications (i.e., theCode Case is generally acceptable but the NRC has determined that the alternative requirementsmust be supplemented in order to provide an acceptable level of quality and safety).

(3) Table 3, “Annulled Unconditionally Approved Section III Code Cases,” contains the Code Casesthat have been annulled by the ASME.

(4) Table 4, “Annulled Conditionally Acceptable Section III Code Cases,” contains the Code Casesthat the NRC determined to be acceptable, provided that they were used with the identifiedlimitations or modifications, but were subsequently annulled by the ASME.

(5) Table 5, “Section III Code Cases That Have Been Superseded by Revised Code Cases on or AfterJuly 1, 1974,” lists Code Cases that have been superseded through revision.

Code Cases that the NRC determined to be unacceptable are listed in Regulatory Guide 1.193,“ASME Code Cases Not Approved for Use” (Ref. 4).

Code Cases provide alternatives to existing Code requirements that the ASME developed andapproved. The new Code Cases and revisions to existing Code Cases listed as approved in Tables 1 and 2of this guide are incorporated by reference into 10 CFR 50.55a. Code Cases approved by the NRC maybe used voluntarily by licensees as an alternative to compliance with ASME Code provisions that havebeen incorporated by reference into 10 CFR 50.55a.

Requirements related to Code Case implementation are provided in 10 CFR 50.55a(b). When alicensee initially applies a Code Case listed in Tables 1 or 2, the licensee must implement the most recentversion of that Code Case incorporated by reference in 10 CFR 50.55a.

RG 1.84, Rev. 34,

Code Cases may be annulled because the provisions have been incorporated into the Code, theapplication for which it was specifically developed no longer exists, or experience has shown that thedesign analysis or construction method is no longer adequate. After the ASME annuls a Code Case andthe NRC amends 10 CFR 50.55a and this guide, licensees may not implement that Code Case for the firsttime. However, a licensee who implemented the Code Case prior to annulment may continue to use thatCode Case until the licensee voluntarily updates its Section III Code of record. If a Code Case isincorporated by reference into 10 CFR 50.55a and later annulled by the ASME because experience hasshown that the design analysis or construction method is no longer adequate, the NRC will amend 10 CFR50.55a and this guide to remove the approval of the annulled Code Case. Licensees should not begin toimplement such annulled Code Cases in advance of the rulemaking. Notwithstanding these requirements,the Commission may impose new or revised Code requirements, including implementation schedules, thatit determines are consistent with the Backfit rule (10 CFR 50.109).

With regard to the use of any Code Case, it is the responsibility of the user to make certain thatthe provisions of the Code Case do not conflict with licensee commitments or regulatory requirements.

(1) The damping values specified may be used in analyzing piping responsefor seismic and other dynamic loads being filtered through buildingstructures provided response mode frequencies are limited to 33 Hz andbelow. Within this range, the Code Case damping should be usedcompletely and consistently, if used at all. [For equipment other thanpiping, the damping values specified in Regulatory Guide 1.61 (Ref. 7),should be used.]

(2) The damping values specified may be used only in those analyses in whichcurrent seismic spectra and procedures have been employed. Such useshould be limited only to response spectral analyses [similar to that used inthe study supporting its acceptance, NUREG/CR-3526 (Ref. 9)]. Theacceptance of the use with other types of dynamic analyses (e.g., time-history analysis) is pending further justification.

(3) When used for reconciliation work or for support optimization of existingdesigns, the effects of increased motion on existing clearances and on linemounted equipment should be checked.

(4) This Code Case is not appropriate for analyzing the dynamic response ofpiping systems using supports designed to dissipate energy by yielding(i.e., the design of which is covered by Code Case N-420).

(5) This Code Case is not applicable to piping in which stress corrosioncracking has occurred unless a case-specific evaluation is made and isreviewed by the NRC staff.

The maximum measured ultimate tensile strength (UTS) of the componentsupport material should not exceed 170 Ksi in view of the susceptibility of high-strength materials to brittleness and stress corrosion cracking. Certainapplications may exist where a UTS value of up to 190 Ksi could be consideredacceptable for a material and, under this condition, the Design Specificationshould specify impact testing for the material. For these cases, it should bedemonstrated by the applicant that(1) the impact test results for the material meet code requirements, and(2) the material is not subject to stress corrosion cracking by virtue of the fact

that(a) a corrosive environment is not present and(b) the component that contains the material has essentially no residual

Each licensing application in which the Code Case is to be used should presentinformation that satisfactorily demonstrates that the subassembly tests adequatelysimulate the pressure loadings. Also, the closure fixture for the test subassemblyshould adequately simulate the rigidity of adjacent subassemblies and alsosimulate the interface loadings from adjacent subassemblies that would resultfrom a hydrostatic pressure test of a complete pump assembly. As a minimum,the closure fixture should impose loads that result in stresses equal to or greaterthan those induced during the hydrostatic test of a complete pump assembly. It isnot intended that piping reactor loadings be simulated in the hydrostatic testing.

1783 Qualification of Nondestructive Personnel, Section III, Division 1 1/14/77
